Answer:
Voy a tomar aspirinas. Tengo dolor de cabeza.
Explanation:
Voy a tomar aspirinas. Tengo dolor de cabeza. In English this means: I'm going to take an aspirin. I have a headache. In Spanish, the terms related to physical pains are formed by the noun "dolor" and the part of the body involved. Dolor de cabeza, dolor de muela, dolor de estómago. There isn't a word to name those pains as in English: headache, toothache, stomachache.
